What if the men attend a Bible study led by a woman for women, because they want to know what it is that their wives are being taught? They aren't there to learn but to discern?  Should they just ask to look over the materials outside of class?  Obviously they should have some concerns over what someone like Beth Moore is teaching their wives. I ask only because I have never heard of a situation like this before but could understand husbands wanting to know just what it is that their wives are learning.
